TOPLINK-5006
Please look at the following exception . Does it mean I have versionLocking policy set for a descriptor . What can be concluded from the trace.
Exception [TOPLINK-5006] (TopLink (WLS CMP) - 10g (9.0.4.5) (Build 040930)): oracle.toplink.exceptions.OptimisticLockException
Exception Description: The object [[email protected]086c] cannot be updated because it has changed or been deleted since it was last read.

This exception happens when you've enabled Optimistic locking, and have two concurrent transactions trying to modify/delete the same object in the concurrent transactions.

I have an object model with Booking and Status objects, where Booking has 1-1 relationship with Status.
Since we're using Webservices, we try to perform update on the object returned by webservice with MergeClone as follows:
Session session = getSession();
UnitOfWork uow = session.acquireUnitOfWork();
uow.registerObject(booking);
uow.mergeCloneWithReferences(booking);
uow.commit();
However, I got SQL Exception when commit:
Internal Exception: java.sql.SQLException: ORA-00001: unique constraint (CS2_DEV_EXERCISE.SYS_C007756) violated
Error Code: 1
Call:INSERT INTO TEST_NGSC_BOOKING (BookingID, Name, version, StatusID) VALUES (101, 'changed', 1, NULL)
Query:InsertObjectQuery(booking[101, changed, null, 1] )
It is strange to me that Toplink generate "Insert" statement, but actually the record is already stored in DB, and the PK matched with the object I passed to "mergeClone" call.
I tried again by reading the Object 1st:
UnitOfWork uow = session.acquireUnitOfWork();
uow.registerObject(uow.readObject(booking));
uow.mergeCloneWithReferences(booking);
uow.commit();
Then I got another exception:
Exception [TOPLINK-5006] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.OptimisticLockException
Exception Description: The object [booking[101, changed, null, 1] ] cannot be updated because it has changed or been deleted since it was last read.
Class> com.cargosmart.toplink.test.Booking Primary Key> [101]
Please kindly advice if I have done anything wrong in my code
Many ThanksFor the case:
uow.registerObject(uow.readObject(booking));
uow.mergeCloneWithReferences(booking);
uow.commit();
The same exception thrown as before:

uow.commit() ?
uow.getUnitOfWorkChangeSet().hasChanges();
If this is false that means there are no changes.
You need to ensure that when the object is sentback
over the wire there are indeed changes or elsewhen
the comparison happens and there are no changes
no
updates will be written.
I was able to reproduce one of your problems(the
unique key violation) but was unable toreproduce
the
optimistic lock exception.I was able to reproduce the optimistic lockexception
as well. On your web services client side code you
have invoked a method that changes the version
attribute on the booking class. The versionattribute
is one that Toplink manages not the developer.Check
to see if this is happening.Thanks for reminding!
Yes, the problem is related to the version field.
I need to take special care on the version value by
performing the "readObject", get the existing version
value and fit into the changed object before
performing mergeClone, and then I was able to commit
the change into DB successfully.I understand that you have to do a "readObject" before you merge to avoid the unique constraint violation exception(the object may no longer be in the cache when you merge especially if you set the Existence check to "Check Cache"). But I am not sure updating the version field is recommended. You may want to confirm that of course. -
We are encountering OptmisticLockException sometimes in our app, when this happens all the other transactions are affected, is there any way to clear the Toplink cache externally? thanks
Thanks, but can you please tell me why Toplnik is issuing an update instead of insert for the object FXSingleLegC.FI120.0#16137966, I have given the list of registered objects and the sql generated, as you
can see the primary key is 0 for the object and Toplink still issues an update statement

We do not have Cache synchronization

There are 4 boxes and each box has one admin and 4 managed servers.

Hi
Document link . http://ftp.unex.es/oradoc/application_server_10g/web.904/b10313/conf4as.htm#1121739
I am going over the following documentation and want to understand the significanace of the following .
Collocation
Although the BEA WebLogic cluster enables you to build an application across several servers, related components in the application must still be localized to a server. When you store several beans on the same server, the beans are said to be collocated.
Collocation in a BEA WebLogic cluster imposes the following restrictions:
When you deploy beans on a single server, you can invoke those beans only on that server. This localizes the beans on a given server, and provides a statically-defined means of collocation.
You must cluster bean Home interfaces, but not instances. When you instantiate a bean, you pin it to the server on which it was instantiated.
For more information, see "Pinning".
JTA user transactions must execute completely on a single server, and cannot span servers.
You must collocate all related beans and objects on a single server to support relationships between beans. To simplify the application, also retrieve source and target objects on the same server.
When you create or instantiate a bean, the bean instance is associated with, or pinned to, the server on which it is instantiated. To localize transactions to a particular server, BEA WebLogic Server pins all instantiated beans in a given transaction to the server on which you run the transaction. If beans are pinned to other servers, you cannot localize the transaction.
You can pin beans to a given server dynamically, either through user transactions or through session beans.
In production we have the following setup
Box A has 4 managed server M1 , M2 , M3 , M4
Box B has 4 managed server M5 , M6 , M7 , M8
Box C has 4 managed server M9 , M10 , M11 , M12
Box D has 4 managed server M13 , M14 , M15 , M16
For initial context lookup we use Multiple-address provider URLs resolving to servers example :
WL.Context.PROVIDER_URL = t3://xxx:2321,xxx:2322,xxxx:2323,xxxx:2324
We do not use JMS Cache Synchronization for cluster and rely on Optimitic Locking.
Problems Experienced
Toplink cache is stale and user keeps hitting the TOPLINK-5006 -cannot be updated because it has changed or been deleted since it was last read. exception repeated.
Could this be due to the fact that Reads and updates probbaly occurs thru different managed servers in a box ?
Thanks ... and appreciate any feedback
LakshmiYes. That is most likely what is happening. You will need to look at cache configuration, refresh queries, and possibly cache coordination. Some additional information is available in Re: Configuration for multilpe nodes.

Hi All,
i'm getting this exception can any one explain why this exception occurs and how to resolve this issue. I achieved a solution by refreshing the respective object, but i expect this might be occured due to commit of same object twice.
Will this exception occurs if we commit the same object twice.
Exception [TOPLINK-5006] :
The Object cannot be updated because it has changed or been deleted since it was last read
Thanks in advance.
Regards,
PraneethPlease post the code that throws the exception.
Also go through the following link regarding optimistic locking -

PraneethInteresting - an urgent Documentation issue.
Or is it perhaps that you need to discuss this with a TopLink expert - in which case you could try the TopLink forum at TopLink/JPA
If it truly is urgent, you should use your Support Contract to contact Oracle Support. -

different tables. I call these methods in my page backing bean.
I also want to JTA in web side. My first methods is done correctly, but second method has an error. I wanto to rollback all transaction.
How can ı do that? with using JTA in Toplink...Yuichi
Did you manage to solve this? I'm doing something similar and seeing the same problem, although they're up to 7.3 SP7.
Any help greatly appreciated.

Upgrading from Weblogic 6.1sp5/TopLink 3.6.3 to Weblogic 8.1/TopLink 9.0.4
Hi.
We are doing the migration from Weblogic 6.1sp5/TopLink 3.6.3 to Weblogic 8.1 & TopLink 9.0.4
We have been reading available documentation and started the migration. We have not had any problems with package ranaming issues and XML DOCTYPES changes.
As we do have a lot of ammedmed querys, we do prefer to use a java class as our proyect mapping descriptor rather than a huge XML.
We are currently porting all our querys to the new system.
As we are doing a lot of changes we are also updating our EJB 1.1 entity beans to EJB 2.0 (maybe in the future we will deploy our EJBs with local interfaces too).
The main problem we are facing right now is with all the querys we had in our toplink-cmp-<bean>.xml files. Even if most of the finders are "REDIRECT" querys that had to be ammendmed we have a good number of "EXPRESSION"s on them.
As far as we are able to see we should move them to the TopLink Project java file in the querys section. The question is: is it possible to declare them in the ejb-jar.xml file into the <ejb-ql> tag (we have seen that the TopLinkImplemented string appears on the <ejb-ql> telling the container who should handle the query, so if Weblogic can be "tricked" to do that "ejb-ql" it may be possible to do the same with a TopLink expression isn't it?.
Another issue we don't have clear is if now all the querys must be either ejb-ql (compliant with the EJB 2.0 standard) or named querys (either TopLink expressions or SQL querys) defined in the TopLink Project java or XML files. What happened with the redirect querys
I would like to point just another issue we have "solved" but we are not really satisfied with how we solved it.
We are using timestamp locking with our entity beans. The shouldBindAllParameters is set to true too and we have the logging activated so we have been able to track down the problem.
The problem seems to be something like this.
You create a new entity bean and TopLink issues a sentence like this against the DB (Oracle 8.1.7 I must say we have also configured the login session to use the Oracle8PlatformSupport)
INSERT INTO FOO(OID,OCA) VALUES (?, ?)
bind => [1, 2004-04-26 13:16:45.251]
As far as we know Oracle 8.1.7 doesn't store the milliseconds (we are using DATE type in Oracle tables) so the ".251" value is stored as "0"
Then we try to delete the entity bean and TopLink sends this sentence to the database:
DELETE FROM FOO WHERE ((OID = ? AND OCA = ?))
bind => [1, 2004-04-26 13:16:45.251]
Then, a TOPLINK-5003 (the object has been modified or deleted since last read) is raised and the transaction is rolled back.
We tried without binding and it works perfect (it seems that the timestamp is treated as YYYY-MM-DD SSSSS in the "to_date" function issued)
As we would like to keep with binding all parameters in order to optimize our database accesses we have changed the default jdbc driver (sun.jdbc...) that is showed when reading the proper property of the login sesion with the oracle.jdbc.driver.OracleDriver. This latest driver seems to solve the problem with the reminders of the timestamps but this brings us a doubt.
If we have configured two datasources in our Weblogic's config.xml file (one for transactional operations, beeing that one also an XA driver as we need to coordinate RDBMS operations with a JMS service, and the other one being a "standar" oracle.jdbc.driver.OracleDriver) why is that the driver used as default by the login method is that "weird" sun.jdbc... driver? Shouldn't TopLink use one (the XA driver I hopefully) of the drivers defined in Weblogic's datasource?
1. Is the issue we are seeing with the timestamp a known bug/problem?
2. Is there a better way to solve it than changing the driver (we are affraid of the "new" issues changing it could raise)
I have seen that with TopLink 3.6.3 and the "default" driver used in the login (it is the same by default on both TopLink 3.6.3 and TopLink 9.0.4) the binded timestamp are "truncated" to the second resolution and it works without any problem.
Thanks in advance.
IgnacioNot sure on all of the issues, but can provide some information on some of them.
Re-directors:
Support was added for re-director to core queries, so now your named queries can make use of re-director if they require advanced dynamic execution. So all re-director queries can become named queries.
Timestamp locking:
In general we would always suggest numeric version locking if you have the choice. I'm not clear on what you are saying about the driver having an effect on the problem, however in general Oracle 8 does not support milliseconds, if you use timestamp locking with local timestamps they will have milliseconds and the database values will not match the ones in memory.
To resolve this you can,
- Use server timestamps TimestampLockingPolicy.useServerTime()
- Clear the timestamp's milli/nano second value through an aboutToInsert event.
- Extend Oracle8Platform.convertObject to clear the timestamp's milli/nano second value.
- If you can use Oracle 9 or 10 there is now a TIMESTAMP type that does support milliseconds.
If a different driver seems to be solving this, it is most likely the database ignores the milliseconds in the comparison, but the driver you are using sends the millisecond to the database incorrectly when binding. -
Help on Decode function in Toplink
Hi,
I have a sql statement like this:
select field1, field2 from table1 where upper(field1) like 'ADELPHI%'
order by field1,
DECODE(TO_CHAR(NVL(LENGTH(TRANSLATE(field1,'A1234567890','A')),0)),'0',LPAD(field1 ,50),field1)
How would I converted this to toplink query?
I appreciate any help you guys can extend to me.I just spent about a half hour writing a response here, and the damned forum timed out on me. #$^!@$#!^!@$%.
Here is the summary:
- Using TL Expressions and EJBQL are to allow Java developers who don't necessarily know SQL to write queries and to facilitate portability/maintainability of the apps. For REALLY gnarly queries, using TL Expressions or EJBQL won't buy you this. I.e., SQL is more expressive and easier for this kind of quer, so it's not easier to use, and frankly with the code needed to support it, it won't be easier to maintain or port... Bottom line, maybe SQL is the best option here?
- If you want to experiment, search for TO_CHAR on this forum, and the decode function in the javadoc. You need to build the expressions in pieces and you can treat expressions as arguments to other expressions -- in other words, you can build an expression like builder.leftPad(50, builder.get("field1")) and use it as one of the key/values in the hashtable to the decode function (in theory).

Multiple Rows Update / Refresh Toplink Query when database trigger involved
Hi everybody!
I have two easy troubles for you; the platform is the same as the SRDemo Toplink version.
1. Multiple Rows Update: I want to update with mergeEntity method, multiple rows for an isolated table; that method receives a parameter that I try to bind with the iterator "dataProvider" but it only merges the first row, not all, any other combination returns an error.
What I want to do is to have a form (like tabular forms in Apex) that lets me update multiple rows in a single page. ¿May anyone tell me how to do it?
2. Refresh Toplink Named Query: I have a list on a page with two columns. From another page, a button does an action that fires a database trigger that updates one of the columns on the list´s page. When I go back to the list, it is not updated; however, the CacheResults´s property is set to false on the iterator.
Thanks in advance,
Alejandro TI didn't use it (yet), but - you might take a look. You'll find a [url http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-plug-ins-182042.html]Timer plug-in on this page. It is a dynamic action which allows you to periodically fire other dynamic actions in the browser. For example use the timer to refresh a region every five minutes. You can perform any dynamic action you want using this infrastructure.So I was thinking: you might use it to run a dynamic action which would check whether something changed in that table (I suppose you'll know the way) (for example, a database trigger might set a flag in some table, timestamp or similar), and - if you find that something really changed - refresh the page.
As I said, I never used it so that's pure theory. Someone else might know better, though. -

SateeshSpring 2.0 provides custom support for TopLink Essentials in Tomcat out-of-the-box. You should follow the instructions here: http://static.springframework.org/spring/docs/2.0.x/reference/orm.html#orm-jpa-setup-lcemfb-tomcat
Essentially, Spring provides a custom class loader for Tomcat and doesn't use an agent.

How do I use toplink with Spring 2.5 and oc4j 10.1.2?
Our existing java server environment is limited to Oc4j 10.1.2 due to being tied to Oracle Forms.
We've added a java 6 jdk to the machine and linked it to a specific container to examine some newer java features since this version of the application server only comes with java 1.4.2.
Does anyone have some configuration steps for getting toplink essentials and spring to work with oc4j 10.1.2? Even with oc4j 10.1.3 in jdev 10.1.3.4 I'm having problems trying to figure out what needs placed in the persistence.xml file verses what needs placed in the spring-beans.xml file.
I'm trying to either use the J2SE option of keeping the connection information in the persistence.xml file (which doesn't work) - it tries to connect to //localhost:1521/orcl. If I try to define a datasource within Spring's xml file, I'm not sure how to tie that into the persistence.xml file. Could I use the oc4j 10.1.2 container provided datasource?
It seems like I'm at a loss as to how to get this working. If you'd like me to post some files, I can do that later on today when I get back to work.
The configuration that I'm trying to do is based on a modified workspace from an ibm developerworks article with websphere, mixing in the ideas from a JPA with Spring 2.0 article from Mike Keith and Rod Johnson. (That article goes pretty far in the configuration information but never provided an example to download...)
Any help appreciated.
Eric (hbg, pa)I'm still at a loss with this. Rather than worry about the older version, for now, I just want to see JPA in action. So, I've decided on just running the Spring 2.5.6 petclinic example out of the samples folder. When I try to do this, after only tweaking the web.xml to use the applicationContext-jpa.xml file, the application does not initialize properly. Here's the stack trace I get:

Anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?
Was there anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?
I don't see anything in release notes ( http://www.oracle.com/technology/products/ias/toplink/doc/11110/relnotes/toplink-relnotes.html ) regarding fixes. Anybody know where I can get that info? We have run into a couple of issues in the previous 11g release (11.1.1.0.1) and want to know if those issues have been addressed in the new release.
Thanks!The two major areas of work in 11gR1 (11.1.1.1.0) are enhancements to EclipseLink included with the its 1.1.1 release as well as enhancements around TopLink Grid (JPA-Coherence integration).
The EclipseLink 1.1.1 fixes are documented here: http://wiki.eclipse.org/EclipseLink/Release/1.1.1
